Recently, climate change is becoming more significant and thus the extreme weather events which lead to the flooding disasters have been increasing. To reduce the impact of flooding disasters, Water Resources Agency (WRA) has presented the updated edition (2nd edition) of inundation potential maps of Taiwan. In addition, WRA has created the vulnerability maps in Taiwan. Based on mapping the inundation and the vulnerability, WRA has developed the flood risk maps of Taiwan, which can provide the useful information to the authorities for making the strategic decisions of the flood disasters. However, the lack of an online service platform that combines the benefit of flood risk database, local search engine and dynamic analysis reduces the accuracy and the efficiency of flood risk assessment for the authorities. Hence, the project aims at establishing an online service platform incorporating the latest rainfall data, the historical flood risk maps and dynamic flood risk assessment in Taiwan for the authorities and the public. The outcomes of this project will enhance the flood disasters prevention and preparedness.水災淹水潛勢圖脆弱度風險平台flooding disasterinundation potential mapsvulnerabilityriskplatform
